Abstract: The invention is directed to a method and apparatus for monitoring liquids ischarged intermittently from a discharge receptacle having a siphon. The liquids originate in a facility in which personnel work with open radioactive substances. Measurements are made of the radioactive charge of discharged liquids in the region of the siphon of each discharge receptacle to prevent contamination of the discharge path into the drainage system. If a radioactive limit value of radiation is detected which is above a specific threshold, discharge of the liquid into the drainage network is prevented. The discharge receptacles are then emptied individually and upwardly.

Abstract: A light for lighting the bowl of a toilet includes a horseshoe shaped web to lie on top of the rim of the toilet. Flanges extend from the web outside of the bowl to hold the web in position. Flanges extend inside the bowl and carry lights. The flanges shield the lights for protection of the lights, and to provide indirect lighting for the bowl. A housing at the rear of the toilet carries a switch for engagement by the lid of the toilet, so the light is turned on when the lid is up. The housing also receives batteries for powering the lights.

Abstract: A toilet has a device for measuring constituents of voided urine. The toilet has a urine reservoir having a surface contiguous to a bowl surface including a urine receiving surface. Urine examined by the measuring device is sampled from the urine reservoir.

Abstract: A toilet seat up indicator is housed in a flat curvilinear shaped housing for fitting underneath the rim of a toilet seat. The housing contains compartments for a flashing light, batteries, an integrated circuit flasher, a mercury switch and capacitors. A cover bearing a message such as SEAT UP is slidably mounted on the housing in mounting slots over the flashing light. The mercury switch activates the flasher when the seat is up.

Abstract: A toilet apparatus is provided in a lavatory having at least one stool, urinal, bidet, or similar toilet structure. The toilet apparatus comprises a detecting sensor for detecting constituents in the feces, urine, or both of a user, and an indicator for indicating or informing the user of his health based upon abnormalities in the constituents detected by the sensor. The apparatus is particularly useful in informing the user of a toilet of his health each time he uses the toilet.

Abstract: A two-piece portable toilet having sight gauges for the flush water reservoir and holding tank. The sight gauge takes the form of a translucent plastic insert having a highlight formed by a diametral groove which permits the liquid level to be clearly ascertained. The inserts are sealed by induction welding in openings in the wall of the reservoir and holding tank respectively.

Abstract: This invention, is a multi-function closet stool, which can really serve the purpose of automatic timing, measuring pressure, flushing and saving water. When one sits on the seat of closet stool, the driving piece pulls the driving steel cable to make timing and piston assembly simultaneously actuate and control arm sandwich on top of a movable piece in the sleeve. When one discharges his urine and stands up, the rear part of seat of closet stool will rebound promptly by the spring; meanwhile, the timing unit begins to count time, then, the driving arm makes the control arm release the movable piece in the sleeve by means of the pulling of timing unit and move upwards by the elasticity of spring. A rubber ring compresses air in the sleeve, the high velocity air will instantly rush in air container through a hole passage, pipe joint, filter and pipe. The air will open a movable lid for the purpose of water-flushing.

Abstract: A human waste storage and disposal system for railroads including a toilet bowl, a discharge outlet connected to the bowl, a flushing fluid inlet for flushing the bowl and a vertically disposed receiver coupled to the outlet for receiving the contents discharged from the bowl. A macerator is coupled to both the receiver and a storage tank for withdrawing waste from the receiver, macerating the same and discharging it into the storage tank. Suitable controls are provided for disposing of the macerated waste in the tank in situ or on demand.
